CALVIN WfERANCIS, 0F OMAHA, NEBRASKAY ASSIGNOR, BY MESNE ASSIGNMENTS,

' TO ARRY FISCHER, 0F OMAHA, NEBRASKA GAS-LIGHTING VALVE.

To all 'whom 'it may' concern:

15e it known that l, tl.\i.viN.\'V. lfnaxcie, i a citizen of the United States, residing at i Omaha, in the county of Douglae4 and State ot' i\'ebraaka, have invented certain n ew and l useful ln'iprovement-s in Gaylnghtinfg l Valves, of which the following ish specitb cation, reference being had therein to the accompanying drawing."-

This invention provides a valve, for controllingltlow of tluid to one or more lamps, having associated therewith meane` whereby, when the valve is partly opened, an electric circuibiii connection with a .spark-gap at each lamp, is closed to light the lamps, and whereby, when the valve is further opened after the lamps have been lighted, the circuit will opened and the. operation of the `spark-gaps discontinued. The dei'icc provided by the invention, by whichthese rcsults are attained, is in a compact torni such afs-may he easily placed on the. dash-board or other part of a vehicle, and itsparte are so arranged that they. will. elhciently and remg systems of motor or other vehicles.

When read in connection with the. de scription herein, the details ot' construct-ion and arrangement of parts contemplated oy the' invention will be apparent from the ac companying drawings, forming part hereof, wherein an embodiment of the invention is iliselosed; for purposes of illustration..

"hile a preferred torni is shown in the drawings, it is to be understood that. various changes can be made therein within the limits prescribed by the chimieA without departingt'rom thenature and spirit ot the invention, and thaty it is not the intention to limit. theinvention in interpretation of the claims herein to the exact. forni shown.-

The end ot thil valve-stem l2 cxtcnds outside of the casing S and has there- .on a tlnnnlrirhcel lf) whereby the Stein may be turned to open and close thtl valve. The valve-stem lt is provided to be setby application of a wrench or the. like to its projecting cnd 20, to permit the iiropeamount of tluid to tlow into pipe 18, itr being intended that this valve Shall 'not be dilstnrbed after it is Sety topcrinit the proptiif tlow. nnlesey thtl pressure from the gas supplywaries. in which case it may he turned to meel; the altered condition.

. member Q1. of non-conductive maturi .l

\'al\'etubc l() at or near its end. and through thisA member at different. places are disposed @crews or other suitable electric connections L and 223. (hi the side of the member il facingr thtl base the Screwa are connu-ted with electric conductors and which conductors` are in circuit with a batter)-v or other suitable souieeof electric energy and with the lamp spark-gaps not shown. 0n the other side of the niembei' 21 the end of the screw 22 yforms'. a contact-point with which a spring Contact member 2G is arranged to contact.- The member 2G is Sccuied to the disk by the screw 23 with which it. has electric connection and by another screw 27, and it is tcnsioned to he normallyl ner at the spark-gapsi the lamps.

and adjacent to the member 21, and on its side facing that member is fixed a spring 29. The spring 29 is so positioned on member 28 that.. when the valve is closed, it will he out of Contact with the springY contact member 2G, and that, when the valve-stem is turned sufficiently to partly open the valve and perspark-gaps.

`Stops 3ft-and 31, respectively on the periphery of member 28 and in the end of the casing 8, are so relatively positioned that they will'engage each other, when the valve is open far enough for a proper liow ot' fluid,

tov preventa complete rotation of lic stem andA its turning sufficiently to permit a sccond engagement of the spring 29 with the contactymember 26 in the opening movement of the valve.

It will be seen that in the use of this device it is necessary to make only one motion of the hand to turn on and light the gas, the'gas-flowi'ng, when tliejs'tem is initially turned and the electric l'circuit thereby closed,

through the pipes 9, 1 4, and 18 and through the 'pipe leadingfrom the latter to the lamps at which the spark-gaps are in operation by the time of its arrival therealr. As soon as the lampsare lighted, the valve-stem is further turned to permit. a normal flow of fluid, and by this operation the contact. is broken in the elect-rie circuit and the operation of the spark-gaps thereby discontinued.

Having` thus described my invent-ion, what l claim as new, and desire lo secure by liet ters Patent, is-

1. The combination, with a valve having a rotatable stem arranged to: control flow of fluid, of a fixed contact-point connectible with a conductor of'an electric circuit. a spring eontactable with said contact-point and arrangedto be normally out of Contact therewith and .also connectible with a con@ ductor of said circit, and on said valvestem a part arranged to engage Said spring and to cause it to Contact with said cont-acti point on initial turning` of said ifalvestem lo open said valve and to permit said contact to bel broken upon further open turning of said valveestem. y
